| Outline of Final Research Achievements |
This research work focused on the development of non-intrusive sensing technique of thermofluid dynamics in order to investigate molecular absorption and formation mechanism of ion layer in the vicinity of interface between different phases. The following techniques were proposed in this work: (i) spatiotemporal distribution of temperature in microchannel by two-wavelength spontaneous Raman imaging, (ii) spatiotemporal distribution of velocity and temperature in microchannel by two-wavelength spontaneous Raman imaging, (iii) molecule concentration distribution in the vicinity of liquid-solid interface by total internal reflection spontaneous Raman imaging and (iv) ion concentration distribution in microchannel by coherent anti-Stokes Raman scattering. It can be concluded that non-intrusive measurements of velocity, temperature and concentration were achieved by Raman scattering, which means that fluorescent particles and dye are no longer required.
